Welding process: О – open arc G – in shielding gas	Wire diameter, mm	Recommended shielding gases and fluxes
О	1,6-3,0	-
G	1,6-2,4	С1 (100% СО₂), М21 (18% СО₂ + 82% Ar)

General characteristics

It is designed for automatic and semi-automatic open-arc metal deposition of strengthening layers for wear-resistant surfaces that require increased hardness and corrosion resistance under conditions off hydro-abrasive and abrasive wear in combination with moderate impact loads.

Application

Typical applications are as follows: hard-facing of parts for slurry pumping stations, loading machines, coal pumps, dredgers and covers for pump housings.

Weldability

The Formation of the weld bead	good
Separation of Slag	good
Deposition Rate, kg/h	4-12
Addiction Weld metal Cracking	moderate
Consumption per 1 kg of wire Weld metal, kg	1.1-1.2
Weld metal Hardness (HRC for 3rd-4th layer, unless otherwise stated)	after surfacing 56-60

Technological features

It is recommended for metal arc deposition at direct current of reverse polarity - DC(+) using extended electrode wire stick-out.
